Wireshark on Ubuntu 11.10 No Interfaces


When installing Wireshark on Ubuntu I’ve run across the issue of no interfaces. Below are the steps to revolve that issue.

Install the setcap executable
$ sudo apt-get install libcap2-bin

Create wireshark group
$ sudo groupadd wireshark

Add your user name to group wireshark
$ sudo usermod -a -G wireshark YOUR_USER_NAME

Change the dumpcap directory to group wireshark
$ sudo chgrp wireshark /usr/bin/dumpcap

Change mode to 750
$ sudo chmod 750 /usr/bin/dumpcap

Grant capabilities with setcap
$ sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

Verify the change
$ sudo getcap /usr/bin/dumpcap

iCamSource UDP Ports


iCamSource requires UDP ports 12000-12100 be forwarded to the computer. UPnP handles well, but a change to pfSense and not using UPnP made me have to look for a solution.

Xen Failed to find an unused loop device


Create a new Xen instance yesterday and had issues getting it started. Already have 4 instances running and the error message “Failed to find an unused loop device” kept appearing.

I could shutdown another instance and bring the new one up, but then the instance I had shutdown would not come back up and had the same error.

Luckily, I ran across the following post that provided all the information.

I created file /etc/modprobe.d/local-loop with one line.
options loop max_loop=64

After reboot, all instances would come up without a problem.

Ben Gray – this quote was meant specifically for you


A politician’s goal is always to manipulate public debate. I think there are some politicians with higher goals. But all of them get corrupted by power.

World-Herald editorial: The need for stability at OHA


The editorial by the Omaha World-Herald is dead on with regards to the OHA board. New board members appointed by Mayor Jim Suttle have caused nothing but difficulties for OHA employees to perform their work.

Ben Gray, Phil Wayne, and Fred Conley are pushing good, hard working employees out of OHA and will continue driving OHA into the ground. Eventually, they will paint themselves into a corner and have no one else to blame for OHA ills than themselves.

Omaha Maker Group


My son and I started attending the Omaha Maker Group (http://home.omahamakergroup.org/) meetings a couple of weeks ago. The group formed only a couple of months ago and meet the first and third Tuesday of the month.

We were not sure what to expect the first meeting we attended, but were happily surprised how much we liked the people and what the group wanted to gain from forming.

We attended our second meeting last nigh and I initiated a discussion about using open source Asterisk to run your own PBX. I felt the discussion was well received and went well. I look forward to initiating more discussions in the future about different topics.

What I like most so far is how well a group of people, mostly students and young professionals, have included my 8 year old son. My son’s interests can be found in others of the group and instead of me trying to figure out everything to keep ahead of him, the group has people that have a great deal of knowledge already. I’m looking forward to continuing with this group as it grows and to see how the group is able to enrich the individual members knowledge.

Accessing SAP from the iPad or iPhone


Accessing SAP using an iPad is a breeze with the app SAPPLAPP. Setup is very quick and easy with nearly full functionality available to the user. I have an SAP IDES ECC 6 system that I access with the iPad and iPhone.

The caveat is that the ITS-Server is installed and running. If you are running ECC 6, the ITS-Server was delivered with the SAP installation. The developer website lists two SAP Notes that may be helpful. I have links to both below.
SAP Note 517484
SAP Note 698329

Basically, on the network where you access SAP through the SAP GUI, try accessing http://:/sap/bc/gui/sap/its/webgui. The host is the server name you find in your SAP GUI setup and the port is most likely 8000.

The instructions below work the same on the iPad and the iPhone. Obviously, the iPad is much easier on the eyes.

1. Launch the application.

2. At the SAP list screen, simply click the plus ‘+’ sign in the upper right hand corner to create a new SAP server connection.
sapplapp System List

3. Enter the SAP server information and save.
SAP System Setup

4. Now, just tap the SAP Server you want to connect with and you’ll be brought to the main SAP menu.
SAP Menu

I have found the app to be very useful, especially when I have needed to take a quick look at something. I look forward to when iPhone OS 4.0 arrives with multitasking and Juniper SSL VPN. With that combination I should be able to access every client from the iPad or iPhone.

For further information, take a look at the developer website.
